Drivers of Deforestation

Drivers of Deforestation

Every year the world loses around 5 million hectares of forest. 95% of this occurs in the tropics. At least threequarters of this is driven by agriculture – clearing forests to grow crops, raise livestock and produce products such as paper. 1 If we want to tackle deforestation we need to understand two key questions: where we're losing forests, and what activities are driving it.

Abstract The recrystallization and precipitation behaviors of rolled Al–20 wt% Zn alloy were investigated during artificial aging. Recrystallization occurred preferentially in the shear bands, and recovery occurred in the elongated grains during aging at temperatures less than 200 °C. The aged Al–20 wt% Zn alloy showed a bimodal structure composed of fine grains and elongated coarse grains.
